CLOVER-HULLER.

Application filed June 23 1913.,

To all whom it may concern Be it known that I, JOHN C. KIsTLER, a citizen of the United States, residing at Clinton, in the county of Henry and State of Missouri, have invented a new and useful Clover-Huller, of which the following is a specification.

The invention relates to improvements in clover hullers.

The object of the present invention is to improve the construction of clover hullers for harvesting machines of the type shown and described in Patent N 0. 934,406, granted to me Sept. 14, 1909, more especially the construction of the means for masticating or grinding the clover heads, the shaking screen for separatingthe heads, straw and other coarse matter from the seeds and chaff, and the hulling mechanism for cleaning the seed and removing the impurities therefrom.

A further object of the invention is to provide adjustable hulling mechanism capable of being arranged to adapt the machine for hulling or threshing timothy, red

top and blue grass clover, millet, oats, rye,

barley and wheat, and equipped with means for presenting a continuous yieldable moving concave surface to the hulling cylinder to prevent breaking of the seed.

"With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure l is a vertical longitudinal sectional View of a portion of a clover huller, constructed in accordance with this invention. Fig. 2 is a transverse sectional view of the same. Fig. 3 is a horizontal sectional view on the line 8-3 of Fig. 2. Fig. 4 is a detail transverse sectional view, illustrating the construction for actuating the shaking screen. Fig. 5 is a detail elevation, illustrating the manner of adjustably mounting the moving concave. Fig. 6 is an enlarged detail sectional view of a portion of one of the threshing or masticating cylinders, illustratingthe construction; of its peripheral engaging face.

Serial No. 775,383.

Fig. 7 is a detail sectional view on the line 7-7 of Fig. 2, ing for rotating the rolls of the moving concave.

Like numerals of reference designate corresponding parts in all the figures of the drawings.

In the accompanying drawings in which is illustrated the preferred embodiment of the invention, 1 designates a relatively large threshing or masticating cylinder, supported below the delivery end of an inclined endless carrier 2 and cooperating with a pair of upper and lower relatively small threshing or masticating cylinders 3 and 4, located adjaeent to the rear portion of the periphery of the relatively large threshing or masticating cylinder 1, so that the clover heads will be operated on successively by the upper and lower cylinders 3 and 4, whereby a thorough threshing or mastication of the said clover heads will be effected. The cylinders l, 3 and 4 are each provided with a rough or rasp-like surface 5, as set forth in the said patent, and the said threshing or masticating cylinders rotate in the direction of the arrows in Fig. 1 of the drawings, and their contiguous portions travel downwardly in the same direction but move at different speeds, the large cylinder rotatin g at a much higher speed than the small cylinders. Any relative speed'may be obtained by varying the diameter of the gears hereinafter described for actuating the said cylinders.

The relatively large cylinder 1 is mounted on a horizontal shaft 6, carrying at one end a sprocket wheel 7 designed to mesh with and be driven by a sprocket chain 8, which operates the inclined endless carrier 2 in the manner shown and described in the aforesaid patent. Any other suitable gearing, however, may be employed for rotating the relatively large cylinder. The shaft 6 has keyed or otherwise fixed to its other end a pinion 9 meshing with a relatively large gear 10, secured to the shaft 11 of the upper relatively small cylinder 3, and motion is transmitted from the upper cylinder 3 to the lower cylinder 4 by gears 12 and 13 of a uniform diameter, whereby the upper and lower cylinders 3 and 4 rotate at a uniform speed. The pinion 9 of the relatively large cylinder 1 and the gear wheel 10 of the upper relatively small cylinder 3-provide for showing the sprocket gear- 1 driving the large cylinder -1 at a higher speed than the small cylinders 3 and 4, but any other form of gearing maybe employed for accomplishing this result, and in practice the Cylinders will be adjustable'toward and from each other to secure the desired engag-smear 'withtheclov'er heads or 'o'ther niaterial operated on. The material after pass ingbetween the large cylinder and thefu'p- ;perand IQWQI'TASIXHLH cylinders will be groun'dFor mastica ted in suelrrnannerfthat g ds g and become .thQroughly separated from the head's,"straw and other' coarse material.

nitligth front par 7119 6 5 are preferably arranged at the center and he nel heel end e ends thereof, as illustrated in Fig. 3 of the drawings. Mounted on one end of the crank shaft is a sprocket wheel 23 receiving -aspr'ocket chain 24,. which extends to and "*meshes with a sprocket wheel 25 fixed to the shaft 6" of the large cylinder, adjacentto the gearing vfor imparting motion from thelarge cylinder to'thesmall cylinders.

-The hulling mechanism, which. is shown coextensive in length with the threshing cylinders owing to its particular arrangement Y iwith relationtothe latter, may be constructied flof preferredlength to secure-the desired of hulling surface. A The hulling mechanism comprises in it'sconstruction a relatively largehulling cylinder 26 and a moving concave. composedofia series of small cylinders or rolls 27, and a' fiexible traveling belt or apronYQS, arranged on and {actuated the said rolls 27. The hulling cylinder 26 is provided \vith an engaging face 29 formed cutting the periphery of the cylinder in a longitudinal direction at a slightaangle, sayten degrees to the radii of same and raising. longitu dinal burs or teeth,* as clearly illustrated in Fig, 6 of the drawings, for engaging the seed. In practice; there will be-about twenty of the said teeth or burs of the engaging face to an inch, but theirsize and ,number may, of course, be varied, T he tra'x' eling belt or apron of the moving concave, which is designed to be conistiguct ed of leather, rubber, canvas, or other pliable and yieldable. material, presents a continuousi lexible yielding moving concave surface to the convex surface of the hulling cylinder and is adapted to prevent the breaking of the seed or grains in the process of hulling the same The endless belt or apron-inpractice will have its ends united by lacing oi other suitable means, and will Zbe; drawn tightly around the rolls or cylinde-rs pfthe moving concave forming an endless covering therefor and constituting a continuous moving surface forv the samead apted to have its tension adjusted by the means hereinafter described. The continu ous concave face of the traveling belt or apron and the adjacent or contiguous portion of the hulling cylinder move in the same direction, but atjdifierent rates of speed. Either the gearing shown and described in the aforesaid patent, as hereinafter fully described or, any other; suitable gearing may be employed for actuating the rolls or cylinders.

The small rolls or cylinders 27, with the exception. of the lowermost one, are mounted, on shafts ,30 having their terminalsextended through slots 31.,0f the side walls htthei e ne 5 and a n h e openings 32 of: adjustable frames The justable frames and connected with adjusting screws 37', which are adapted to stretch the traveling belt or apron to the desired tension by adjusting the lower end roll or cylinder. The screws 37, which are mounted in threaded openings of terminal flanges 38 of the adjustable frames, are suitably connected with the slidable bearings. Either or both end rolls or cylinders of the moving concave may, of course, be adjustably mounted in the manner shown. The adjustable frames are also provided at their upper and lower ends with projecting lugs or flanges 39 receiving one end of right and left hand threaded screws 10, which also engage threaded openings of fixed lugs or flanges 41 of the casing 15. The lugs or flanges 41 are preferably formed integral with attaching plates 42, which are riveted or otherwise secured to the outer faces of the side walls of the casing 15. The right and left hand threaded screws are provided with central polygonal wrench receiving portions $3 to enable the screws to be readily rotated by a wrench or similar tool to move the concave toward and from the moving cylinder to adjust the hulling mechanism to enable it to operate on various kinds of seed.

The casing contains a sieve or riddle 14 onto which the seeds and hulls are dropped as they pass between the hulling cylinder and the moving concave. The seeds passing through the riddle 4a are exposed to the blast from a fan 4-5, arranged at the front of the lower portion of the casing 15 and serving to discharge the hulls and chaff through an opening l6 in the rear wall of the said casing The clean seed drop into a trough 47 formed by the lower portion of the casing 15 and receiving a screw conveyer 4-8 for delivering the seed to an elevator as at the upper end of which the seed is discharged into a suitably support ed bag or receptacle (not shown), as explained in the aforesaid patent. A sprocket wheel 50 is secured to one end of the shaft 51 of the screw conveyer, which is driven by a sprocket chain 52, extending from the screw conveyer to the fan shaft The fan is designed to be driven'by a belt 54 arranged on pulleys 55 and 56, mounted, respectively, on the fan shaft 53 and the shaft 57 of the'hulling cylinder. as set forth in the said patent, but the gearing for operating the fan and the conveyer may be arranged in any other suitable manner. The riddle 44, as explained in the said patent, is designed to be hung in such manner' as to enable it to be vibrated by an eccen tric or other suitable actuating means. The shaft 57 of the hulling cylinder carries a pinion 58, which meshes with a relatively large gear 59 mounted on one end of the shaft of the central one of the series of rolls 27. This will cause the concave face of the traveling belt or apron 28 and the adjacent portions of the hulling cylinder to move in the same direction at different speeds. The rolls 27 are simultaneously rotated by sprocket gearing consisting of sprocket pinions 60 fixed to the shafts of the rolls 2'? and a sprocket chain 61 arranged on and meshing with each of the sprocket wheels 60.
